2 Claims.

Our invention relates to a pipe for smokers use and may be said in general to refer to tobacco pipes and cigar and cigarette tubes or hol-ders.

The invention relates more particularly to a 5 pipe having means for cooling the smoke passing therethrough so as to render the same most pleasing to the taste and prevent burning of the tongue and mouth, as well as to provide an improved construction of the same which will furnish a better taste when smoked, will draw more easily and will be more hygienic than pipes commonly in use for its parts may be easily disassembled for cleaning and other purposes.

In the construction of the pipe there is means for providing a sinuous or circuitous path for the smoke of some considerable length, together with means for enabling a very complete radiation of the heat so that the smoke is cooled eifectually before reaching the mouth-piece at the end of the stem.

Amo-ng the many objects of the invention which may be mentioned may be name-d the production of a device of the kind described which is simple, compact, convenient, durable, satisfactory, reliable and efficient for use wherever it is found applicable and suitable.

With this and many other objects in view, the advantages and benets of the construction herein shown and described will be obvious to those skilled in the art from the disclosure hereinafter made of the essential features and the details of the invention; and to this end, therefore, the invention may be said to consist in the novel construction, arrangement and combination vof parts and in numerous details and peculiarities thereof as herein shown and described and then more conveniently pointed out in the claims.

In the accompanying drawing illustrating our invention, wherein like reference characters indicate like or corresponding parts,

Fig. 1 is a longitudinal sectional view of our improved pipe.

Fig. 2 is an outside elevational view of the same.

Fig. 3 is an enlarged partial sectional view of the stem and the foraminous or sieve-like members combined therewith and composing a part lthereof to permit effectual heat radiation from the smoke as it passes through said stem.

Fig. 4 is a transverse section of the same on the line 4 4 of Fig. 3.

Fig. 5 is an enlarged sectional detail view of a portion of the inner end of the mouth-piece and the elongated rod provided with a series of baffle devices and inserted through the stem.

Fig. 6 is a sectional detail on the lines 6 6 of Fig. 5 and shows the faces of a pair of contiguous baille plates.

Fig. ris a cross section on the line 'I-'l of vFig. 5 and indicates the air passage for the smoke after it leaves the baffles and enters the mouth-1-v substantially at the extreme bottom so that the f smoke may have eXit from the complete combustible area of the contents.

2 designates a mouth-piece of any qualified design or shape having therein a central passage 3, through which the smokeflows to the mouth and in which because of the peculiar construction of the stem and its several advantageous characteristics the smoke will be found to be considi erably and markedly cooled by the time it reaches the mouth, the radiation being effectual.

The mechanism of the pipe which may be treated as the equivalent of what is ordinarily known as a pipe-stem, that is to say, the member between the bowl and the mouth-piece, is constructed of several features which by reason of their combination and co-operative relation produce the results which demonstrate the value of our improved pipe.

The description of these parts of the stem is as follows: v

The metallic tube of any preferred material, but usually some thin, but stiff metal, 4, is inserted and held tightly in the lower portion of the bowl I, butl is usually withdrawable for purposes of cleaning or adjusting. This thin tube enters the lower portion of the bowl far enough to provide a strong holding connection, and it is long enough to reach to the mouth-piece at a suitable distance therefrom so that the length of the stem and the mouth-piece together may be a reasonable one for the length of the pipe, but maybe obviously variable and prepared in different sizes for different grades and sizes of manufacture.

At a suitable point on the tube 4 where it abuts against the bowl, in order to form a close joint thereagainst, is an integral collar 5, and at the end of the tube 4, the most remote from the bowl I, is a similar integral collar 6.

Between these.

-may have any desired length.

two collars 5 and 6, and closely surrounding the thin metallic tube or pipe 4, is wound a member of finely meshe-d fabric II, which is folded back and forth upon itself in a manner similar to a bellows construction so that within the pouches of the mesh at I4, are open spaces of considerable size which obviously alternate with each other so that every other one is open against the tube 4, and every other one alternating therewith is open against the wall of an outside meshed fabric I0 surrounding the element I'I in a close and tight manner, said cylindrical sieve-like element I 0 being firmly secured at its ends to the disks or collars 5 and 6, as clearly portrayed in Fig. 3.

The specific and exact form of the bellows-like member II may vary within wide limits and the alternate pouches I4, some of which members are open directly to the tube 4, while the rest of the members are open directly to the external sieve cylinder I0, may be smaller or larger and rectangular or other angular as preferred, or .curved if desired, in order to form recesses, the object being to provide these alternative bends in the bellows material to enable the heat from the smoke to be radiated therethrough easily and promptly, and enabled to pass through the tube 4 to Lthe sieve I0 and thus be carried into the atmosphere. The bends of vthe member II may be in the form of flutes or corrugations to in- 'In some instances a textile maybe used in one or both cases, but usually it will be a metallic fabric. The object of course is to provide efficient means for withdrawing the heat from the smoke and :residue of combustion and this is accomplished in a most desirable and satisfactory way -by .these iforaminous elements. Y

It will be Yobserved therefore, 4that alternate portions of the device II come into immediate contact with the tube 4 and the outer sieve yIl), whereby the surface for heat conduction is `greatly increased.

lThe passage I3 which leaves vthe bottom of the lbowl I delivers directly into the end of lthe tube 4 which is inserted into the adjacent part of saidzbowl.

The mouth-piece 2 against which the collar 6 :abuts when `the parts are assembled in service position, carries an integral sleeve 'I of vsmaller dimensions, which enters the adjacent end of the tube 4, and therewith forms a suitable joint so Athat collar 6 which directly surrounds `the sleeve I may be in close conjunction with the end of :the member 2, and through this sleeve 'I runs a passage I2 through which the smoke from the interior tube 4 reaches the delivery passage 3 inthe mouth-piece ,2.

'There may obviously be any number of these passages I2, (see Figures 5 and 7). Within the sleeve "I is firmly secured the end of a rod or stem 8, which is adapted to be inserted into the tube 4 and has a length sufficient to enable it to reach `entirely through or nearly so if desired, the said tube 4, although obviously the stem or rod 8 It is equipped with a series of alternating cam-shaped baille devices preferably composed of curved or semicircular tabs or plates 9 which are shown in side view in Fig. 6, two of these baffle plates being there indicated. rIhey are completely semi- 5 circular in shape, or a little more than a complete semi-circle, one portion of the plate being a complete semi-circle and the other portion on the other side of its axis having a slightly curved diametrical line, which is tangent to the surface of the rod', the semi-circular portion of the baflles being in Contact with the inner tube, and these baifle plates alternately project in opposite directions so their peripheries come into contact closely with opposite interior arcs of the 1 tube, 4. These baffle devices ll the interior space of the tube 4, and cause the smoke to follow a tortuous passage, delays its transit and gives more time to dissipate the heat in the smoke by radiation through the wall of the tube 2 4 and the surrounding foraminous elements.

We reserve the liberty of varying the exact form of the obstacles 9, in order to yaccomplish the best results, but it will be understood that they serve as obstructions for the passage of the smoke and baille it in its movement.

When the rod 8 carrying the projections 9 thereon is inserted into the tube 4, and the latter has been connected with the bowl, it will be evident that parts of the pipe are completely as- 30 sembled for use for the entrance `of the rod B` which is carried by the mouth-piece 2, supports the latter on the tube 4, which is itself supported in the bowl, rand when the parts are thus put together, the external cylindrical sieve I0 is ushg35 As the smoker uses the pipe and applies suc- 45 tion at the mouth-piece the smoke ensuing upon combustion of the contents of the bowl is drawn through the stem toward Athe mouth, but the ow of the smoke is interrupted by the bailles so that the column of smoke moves slowly, givingff it time to radiate its heat through the mechanism provided for that purpose which of course performs a filtration act upon the tobacco residue.

The sieve-like casing and the bent inner gauzej or mesh receive and quickly deliver the heat units and radiate them outwardly into the atmosphere.

It has been found by practical demonstration that the cooling effect upon the smoke is mostfi'i marked so that the result of the combination of parts in their effective operation is of great -use and value. If the smoke which enters the mouth of the smoker has been previously cooled to a large extent, as is possible with our improvedg pipe, there is far less tendency to quicken the flow of saliva from the salivary glands and therefore obnoxious expectoration is eliminated. Further there is an absence of the usual objectionable collections in the bottom of the bowl and other-7. advantages too numerous to mention are the result of the use of the various parts related together as we have explained.

It will be further understood that the principal features of our invention which have been` set forth herein, may be readily applied to many and various forms of smoking pipes wherein by some slight change in design and without departing from the essential features of the invention, the same desirable results can be attained,

With respect to the form and material of the mesh sieve or strainers IG and l, it will be understood that the neness or coarseness may vary as also the shape and size, and in respect of the member ii its undulations or convolutions whether on the convex or concave side may vary greatly in all respects, particularly with regard to the bends and pouches alternating as shown, or in any other way. Therefore when a large volume of cool outside air passes through the interstices of the mesh and cools the smoke owing through the inner tube of the pipe, these various cooling members will furnish large radiating surfaces for the heat contained in said smoke, thereby cooling the latter very effectually and enabling the smoke when it arrives at the mouth to have a very alluring taste and character.

What We claim is:

l. In a pipe having a bowl, a mouthpiece, and a stem connecting the bovvl and mouthpiece, a passage through the bowl, stem, and mouthpiece, a tube positioned within the stem passage, a central rod of less cross-sectional dimension than the cross-sectional dimension of the stem passage Vand baie members in staggered relation secured to the rod, each baille extending from one wall surface of the passage to the oppositev side of the rod whereby an open tortuous passage is provided within the stem passage.`

2l. The combination with a pipe having a bowl and a mouthpiece, a stem having a central tube, collars adjacent the ends of the tube, a member of finely meshed fabric surrounding the tube,

a cylindrical perforated element surrounding the mesh fabric and secured at its ends to the co1- lars, said mesh fabric consisting of a cylindrical member having a plurality of folds intermediate the ends thereof and engaging the tube, the cylindrical element, and the collars, and a baille member positioned within the tube, said baie member having a central rod of smaller diameter than the tube and substantially cam-shaped baiiles at spaced intervals on the rod, each baffle having an edge thereof of semi-circular form and an adjacent edge tangent to the surface of the rod, the semi-circular portion thereof being in contact with the inner tube whereby a tortuous smoke passage is provided in the stem.
